Title: Two-dimensional matrix switching logic - is employed in transmitting signals to liquid crystal digital indicator
Inventor: HEHLEN ROBERT
IPC: G09G3/36
Filed: 1975-01-17
Abstract: Two-way switches consisting, for example, of an inverter and two MOS gates are connected to each of the columns and lines of a matrix. The switches are supplied with square wave signals KM oscillating between voltage levels of / 3Vs and Km oscillating between voltage levels of Vs and 2Vs. The frequency of these square waves is some multiple of that of the control signal S. The switches are operated by the control signals S and the supply of output voltages to the matrix for different inputs and switch positions. Thus a control signal of S = 1 going to the switching circuits of both a column and a line results in an output voltage amplitude of 3Vs at the corresponding intersections and a resulting energisation (Vs = trigger voltage) of the associated element.

Title: Protection circuit employing ferrite cores - with emitter-follower connected transistor in output winding of lattice end element
IPC: H03K19/003
Filed: 1976-07-23
Abstract: The monitoring or protection circuits employing ferrite lattice cores (L1, L2) are connected in cascade error signals can be induced in the external output circuit wiring which can cause incorrect resetting of the flux in the second lattice (L2) without a corresponding change of state in the first (L1). The problem can be largely overcome by connecting the output winding (WO) of the first lattice (L1) to the base of the planar transistor (T2) connected as an emitter follower, and feeding the reset winding (WR) of the lattice (L2) connected in cascade. Using a planar transistor in this configuration causes its output impedance to limit the rise and fall times of the magneto-motive force produced by the output winding and thereby give a large measure of immunity against fast-rising spikes.
